GUSTAV GOLDMAN, oF- BALTIMORE, MARYLAND. PROCESS OF MAKING FABRIC CONTAINING HAIRCLOTH- mg Haircloth, which process is fully set forth in the following specification.

" This invention relates to a fabric consisting of a matted or felted mass of fibers with 'a'fsheet of haircloth incorporated therein. In

an application, Serial No. 183,823, of even d'ate herewith I have described and claimed a fabric of this kind; and the object of the present invention is to provide a process by which such fabric may be rapidly and cheaply made. I With this object in view the invention con- 1 sists in laying down a layer of animal, vegetable, or mineral fibers, or mixtures of these, ih a loose flufi'y condition, superimposing a layer of haircloth thereon, and then laying another layer of the .fibers upon the haircloth, after which the whole is treated in such way as to unite the two fiber layers and the haircloth layer into a coherent mass. This treatment for uniting the layers may vary considerably in character without departing from the invention. Preferably the treatment consists in uniting the fibrous mass together and to the haircloth .by means of a binding .material which is introduced in a dry finelydivided form betweenthe fibers of the mass and then converting the dry material into an active binding agent b the application of heat or of moisture, or 0 both heatand moisture, preferablyin the presence of pressure,

'after the manner set forth in my application, Serial No. 171,288,

filed August 29,- 1903. In some cases, however, when the fibers or I mixture of fibers employed is of a character which will permit of the'uniting of the fibers into a coherent mass by-rubbing, as in the process of making felt, 'thetreatment for uniting the fibers-with the haircloth between them consists in rubbing'the' fibers in the presence of a suitable binder, as a soluble f 1 soap, then passingthrough afixing solution,

"(as an alum solution,) and .g glain in the presence 'of heat and ressure. and knit together with the haircloth incorpo rated therein. i

then rubbing is results in a' mass of fibers close y bound While it is generally referred to, place the haircloth between two fi l as indicated above, this is not essential, as

haircloth with large open meshes may be laid upon a film or layer of ing wool, the moisture is ms orlayers of fibers,

In the actual practice of the invention the following specific method is preferred and has been found to give the best results viz.,'

a filmorlayer of the desired fibers is laid,

down in a light fluffy as it comes from the doffer of a carding-machine.

Zinc resinate in a dry finely-divided fibers, and because of their condition, preferably condition is then dustedulpon the layer of ight flufi'y condi-- tion much of this finely-divided zinc resinate sifts in among the fibers, while part ofit.re-' mains upon the fibers composing the part of the film or layer. cloth is then superimposed layer and finely-divided zinc resinate'd-usted or otherwise distributed thereon, though this ulpper A-layerlof airupon ,the fibrous distribution of the zinc resinate upon the haircloth may-be omitted in some cases. I A

film or layer of the fibers in light fiulfy condition is then laid upon the haircloth 'andfinelydivided zinc resinate dusted thereon. The

two layers of fibers with the haircloth between them are then subjected; to heat and' ressure, preferably in the presence of steam. l or mechan ical convenience, continuity of operation, and economy of production this is accomplished by including the fibers and haircloth between two belts, one or both of which carry moisture, and passing said belts" between heatedrollers, thus fusing the zinc resinate and converting it'into an active waterproof binding agent, serving to unite the whole into one coherent mass. With certain kinds offibers, as wool or mixtures containan advantage, as the resultin fabric is more resilient; but with other fi bers--as cotton, for example the heated rollers are used in moisture unless a very desired 1 It will be understood thatthe haircloth layer maybe of the kind in which both the weft and the warp are of hair or in which one theabsence of' I hard stiff product is of these is of hair and the other of any difler ent fiber.

While the binding materialis herein described as being introduced-among the fibers it is not meant to thereby in a dry form, state that the material is wholly free from all trace'of moisture, but only that it is so far dried that it can be finely divided and readily .introduced between the fibers.

Manifestly the two films or layers of fibers IIO might be first treated with the binding material after the manner set forth in my application Serial No. 171,288 above referred to, and the haircloth then interposed between them with suitable means, as zinc resinate, for binding the fibrous layers to the haircloth and then treated with heat and pres- I sure; but the method hereinbefore described is preferred as being more economical and producing a superior product.

While I have described herein the specific process of incorporating the haircloth in the fibrous mass by rubbing in the presence of a binder, such as 'soap, and then passing through a fixing solution, as an alum solution, and again rubbing, because said specific process is within the broad invention herein set forth and is meant to be included in the broad claims hereof, nevertheless the said specific process is not specifically claimed herein, as it forms the subject-matter of anotherapplication of even date herewith.
